Lemon balm contains chemicals that seem to have a sedative and calming effect. It might also reduce the growth of some viruses and bacteria.
People use lemon balm for cold sores, anxiety, stress, insomnia, indigestion, dementia, and many other conditions, but there is no good scientific evidence to support many of these uses.
Uses & Effectiveness
Possibly Effective for

- Stress. Taking lemon balm by mouth increases calmness, memory, and alertness in adults under mental stress. Taking lemon balm along with other ingredients might also reduce stress.
When applied to the skin: Lemon balm is possibly safe for most adults. It may cause skin irritation.
